Why have bytes in the first place then? A packed string does count here. 
IBM started this mess with the 360 and 32 bits, and everybody 
followed.Is Fortran I/O the BIBLE on character data.
IBM never seemed even to follow one character set encoding even with the 
similar machines like the IBM 1130.

We don't have opcode space (now that we are 32 bits) to give a byte 
LOAD/STORE but you can buy extra hardware for string functions seems to 
have been the marketing idea back then.

Since punchcards I think had a 16 bit encoding, lack of byte data
was not big problem. Who used paper tape on a 360?
